PATENT @rrica WILLIAM A. SHEPHARD, OF lVAUKESl-lA, \VISCONSIN.

SLED.

SPECIFICATION forming part of Letters Patent No. 766,290, dated August 2, 1904.

Serial No. 206,839. (No model.)

To all wit mt it may concern:

Beit known thatl WILLIAM A. SHEPHARD, a citizen of the United States, and a resident of "aukesha, in the county of \Vaukesha and State of 'isconsin, have invented certain new and useful improvements in Sleds; and I do hereby declare that the following is a full, clear, and exact description thereof. My invention has for its object toprovide simple, economical, and efficient means in connection with a pair of coupled bob-sleds by which to readily convert the same at any time into a vehicle on wheels, said invention being hereinafter more particularly set forth with reference to the accompanying drawings and subsequently claimed.

Figure 1 of the drawings represents a partlysectional side elevation of a pair of coupled bob-sleds and means in connection therewith for converting the same into a vehicle on wheels, the view being indicated by lines 1 1 in the second figure and illustrating the conversion; Fig. 2, a plan View of what is shown in the preceding figure, parts being broken away; Fig. 3, a transverse sectional view indicated by line 3 3 in the fourth figure; and Fig. 4:, a vertical longitudinal s tion of a fragment of the vehicle, this view being indicated by line a at in said second figure.

Referring by letter to the drawings, Arepresents the beam of a forward bob-sled; B, the beam of a rear bob-sled; C D. bolsters on the beams, and E a reach connecting the bolsters. The beam of the forward bob-sled is put into swivel connection with the overlying bolster C, as is customary, and suitable braces are employed in connection with the reach and both bolsters, as is also customary. The ends of the sled-beams A B are bolted in angular brackets that abut the ends of said bolsters and extend along their sides. One; side of cach bracket extends outward from the head 7) of samefthat abuts the end of the corre- ,sponding sled-beam, and this extension is bent at a right angle to form an arm r, parallel to said head. Between its head b and arm 0 each bracket is provided with an upper apertured lug (i, and a spindle F is supported by said head and arm. the inner end of this spindle being enlarged and engaged with a recess pro- 1 vidcd in the corresponding end of a side beam. Ears (d of the brackets are bolted to the sledfenders. i

Loose on each spindle is the upper end of a crank Pr, provided with an inner lower stud e, on which a wheel H is arranged to turn, the wheel being held upon the stud by any suitable means. Between each crank and the adjacent wheel one end of a link is engaged by the stud on which said wheel has its bearing, and the other end of the link is shackled to the depending vertical arm of about rod J, there being a horizontal arm of this rod loose in the lug d of one of the brackets aforesaid. A stop-collarf is provided on this horizontal arm of each angle-rod J to at times abut the guide for same.

The ends of a circle-bar K are coupled to the rods J that pertain to the forward bobsled, and this circle-bar plays loose in a clip 57, depending from a rack-bar L, guided on anti- Clipped fast to the rack-bar L-is a suitably-bent rod M, coupled at its ends to the rods J pertaining to the rear bob-sled.

Meshed with the forward rack end of the bar L is a pinion l rigid on an arbor P, that has its hearings in the forward ends of a pair of arms Q, made fast at their rear ends to the front bolster. A worm-wheel R is also rigid on the arbor. One of the arms Q and a brace S, connecting both of said arms, are provided with b arings for a vertical worm-shaft T, in mesh a 1th the worm-wheel, this shaft being provided with an upper crank or hand whccl U convenient to the driver of the vehicle.

The worm-shaft is operated in one direction to cause backward movement of the bar L in connection, through the circle-bar K and rod M, with the right-angle rods J, and these rods being connected by the links I with the StIClS (3 of the cranks G said cranks are moved out of normal position (indicated by dotted lines in Fig. 1) to swing the wheels 'l-l down to working position, the bob-sleds and load thereon being correspondingly lifted to bring the runners of said sleds off the adjacent surface on which they would otherwise travel, the throw of the aforesaid cranks being limfriction-rollers h, hung in yokes 2', suspended from the reach above specified.

ICC

ited by the stop-collars f of the aforesaid rods coming into contact with the guide-lugs (Z of the brackets that are fastened to the ends of the sled-beams. Reverse operation of the rack-her results in throwing the wheels out of Working position and lowering the bobsledsgvith their load, until the runners of said sleds ere again on the opposing surface.

From the foregoing it will he understood that the vehicle can be readily converted from one on runners to one on Wheels in order to ease the of same over here places occuring in snow or ice reeds, and this conversion does not interfere Withth e pivotal turning pley, of th forward hob-sled. it also follows that the cons/'ersion of the vehicle from e sledto a truck makes it practical to utilize thevehicle as a carrier at all times. V

W ile l have shown what is now e preferred means for swinging the cranks toloring the Wheels therewith in and out of Working po sition, other means rosy be devised for the same purpose without departure from invention, and my improvements niey he ep plied to e sing e long sled as well as to a pair of coupled oo sleds,

Having thus described invention, whet I claim as new, and desire to secure by Letters Patent, is

1'. A sled, spindles in connection with ends of the sled-beams, cranks loose on the spindies, Wheels csrried by the crenks, endrnesns for ectunting the cranks to bring the heels on and of" the opposing surface, said sled he ing lifted clear of said surface w ien said Wheels are swung into working position.

2. A pair of coupled bob-sleds, spindles in connection with ends of the sled-beains, cranks loose on the spindles, Wheels carried by the cranks, and means for actuating the cranks to bring the wheels on and of? the opposing sur-' face, said leds being lifted clear of said surface when said Wheels are swung into Working position.

i 3. A pair of coupled bob-sleds, brackets st- .te'ched to the ends of the sled-beams, guidelugs on the brackets, cranks loose on spindles in the brscheis, Wheels carried by the cranks,

angle-rods engaging the guidedugsoi' said brackets links connectin seid cranks end "lessee rods, and means in connection With the aforewa-rd of said guide-lugs to at times abut the same, links connecting said cranks and en- 'gle-rods, and means in connection With these rods for actuating the aforesaid cranks to bring the wheels on and oil opposing surface, said sleds being lifted clear of said surface when said Wheels are swung into Working position. l

5. A pair of coupled bob-sleds, bracketsetteched to the ends of the sled-beems, angleiods for which the brackets are provided With guide-lugs, crenks loose on spindles in said braclnts, Wheels carried by the cranks, links connecting the cranks and angle-rods e reckber, in rigid connection with the rear anglerods, :1 circle-ber having loose play in connec tion with ssid reek-bar and coupled at its ends to the-forward angler-eds, e rack-her pinion fest oneu suitably-arranged arbor, and means for rotating the arbor.

6.- 21 pair of coup-led hob-sleds, cranks hung from ends of the sledheerns,engle-rods guided in connection with said beams and linked to the cranks, e thrust-ber in rigid connection with the reer angle-rods, a, ircle-ber having loose play in connection with the leer aforesaid end coupled at its ends to the forward angle-rods, and means for reciprocating the thrust-her. c

In testimony that I claim the foregoing l have hereunto set my hand, at Weukesha, in the county of ,Wsukesl enc State of Vfisconsin, in the presence two Witnesses.
